The Rams fired their coach on Monday. Special teams coordinator John Fassel will serve as interim coach. The Rams are at Seattle on Thursday night.

Fisher was the team’s coach since 2012, and compiled a 31-45-1 record with the Rams. He oversaw the move from St. Louis to Los Angeles this past offseason.

The lack of success on the field, capped by a 42-14 home rout at the hands of Atlanta on Sunday, spelled the end for Fisher, who tied Dan Reeves with 165 career regular-season defeats. That’s the most in league history, and Fisher has the lowest winning percentage (.512) among coaches with 130-plus losses .

Los Angeles is 4-9 this season and has scored a league-low 194 points.

“Making a decision such as this, especially during the season, is one of the most difficult in sports,” Rams owner Stan Kroenke said.

“I have great respect for Jeff as a coach, person, father and friend. He has worked tirelessly despite some challenging circumstances. He played an integral role in helping this team make history in returning the NFL to Los Angeles, and we always will be grateful for his commitment and dedication to our organization.”

Fisher, 58, went 147-126 as coach of the Houston Oilers/Tennessee Titans and helped that franchise in its relocation. He led the Titans to the 1999 AFC championship.

Long respected in league circles for his work on the NFL’s competition committee, Fisher never found success — or a franchise quarterback — with the Rams, who went 7-8-1, 7-9, 6-10 and 7-9 in his four full seasons.

They traded up for the first selection in this year’s draft and took Cal’s Jared Goff, but he rode the bench for much of the season behind journeyman Case Keenum as LA started the schedule 3-1. Fisher finally turned to Goff in Week 11 and the Rams dropped all four of his starts.

Kroenke said in his statement that “this is the right time to make a change as our performance has not lived up to my or our fans’ expectations. We all are focused on improving as an organization and building a team that makes Los Angeles proud. Our mission is to celebrate a Super Bowl title with our fans in Los Angeles. Today is the first step to bringing us closer to that goal.”

Floyd arrested

Arizona Cardinals wide receiver Michael Floyd was arrested early Monday on charges of driving under the influence and failure to obey a police officer.

Floyd was found unconscious behind the wheel of his running vehicle at a Scottsdale intersection shortly before 3 a.m. MST., police said.

Police said Floyd also was charged with obstructing a roadway.

He was booked and released from the Scottsdale jail at 4:58 a.m., police said.

Coach Bruce Arians said he was gathering as much information as he can to determine “what our options are going forward.”

“Right now it’s way too soon to know exactly what happened and what can be done,” Arians said.

He said that league rules probably prohibit any suspension until the legal situation is resolved.

Arians said he had spoken to Floyd and probably would have more to say on the subject on Wednesday, when the Cardinals resume practice.

Stafford should play

Detroit Lions coach Jim Caldwell says quarterback Matthew Stafford’s finger injury should not prevent him from playing this weekend against the New York Giants.

The middle finger on Stafford’s right hand was taped up and covered by a white glove Sunday, when he threw for 223 yards in a 20-17 win over Chicago. Stafford had an interception returned for a touchdown in the fourth quarter.

Caldwell said the injury affected Stafford against the Bears, but he should be able to practice.

Tannehill injury

Ryan Tannehill was back at the Miami Dolphins’ complex Monday, his left knee injury less serious than first feared.

The injury was diagnosed as a sprained ACL and MCL, coach Adam Gase said, meaning Tannehill will avoid surgery.

It remains unlikely he’ll play again this season, and Matt Moore will make his first start since 2011 on Saturday against the New York Jets.

When Tannehill was hurt Sunday against Arizona, the Dolphins (8-5) feared a torn ACL that would require surgery and a long, arduous rehabilitation. The Dolphins learned the final diagnosis late Sunday.

“Better than what we thought,” Gase said. “I was happy for him. That’s a hard injury to come back from and rehab. It’s a long, long process.”

ACL surgery generally requires at least a nine-month recovery. Gase said the Dolphins don’t know how long Tannehill will be sidelined by the sprained knee, but it’s questionable whether he would be available even deep into the postseason.

Ratings winner

The Giants’ win over the Cowboys on Sunday night was the most-watched prime-time NFL telecast this season.

It also drew NBC’s biggest audience for a Sunday game since Week 1 of 2015, according to The Nielsen Company.

A total audience of 26.7 million viewers across NBC and NBC Sports Digital platforms tuned in. The 26.5 million viewers solely watching on NBC was a high for a prime-time NFL game since 1989. Those numbers also were up 26 percent from the Week 14 game last year, Patriots vs. Texans.

TV viewership for Cowboys-Giants peaked at 28.1 million from 11:30-11:35 p.m. EST for the game’s final minutes.
